Without having made any benchmarks, I have a few points to add.

1) http only uses one TCP sessions, on busy box that can make a
   difference.
2) there are several very tuned httpd's out there, while my
   impression is that virtually no development has taken place
   on ftpd's in recent years.

BTW: which ftpd does people run ?

- ftp.FreeBSD.org run's the FreeBSD native ftpd (with the setjmp/longjmp
  removal from -current)
- ftp.dk.FreeBSD.org run's proftpd so I can limit the number of
  concurrent connections from the same IP address, the reason is
  that this box is quite limited with regard to memory, and it
  runs cvsup servers too.
